I'll spread these buildings over a few posts, as there will be too many images for a single post.
All of the real life buildings are side by side on South Anderson St, Los Angeles. In the game, they are side by side on Popular St, La Mesa.
The real life Philip Senegram Co building has been replaced by an unnamed warehouse from Mesquit St (up 5 or 6 posts). The name on the building has been transferred to the loft apartments building, & is now called McGrory Furniture.
631 South Anderson St, Los Angeles.
It's amazing how efficient you are at finding things. Great work on finding this one in particular.
That's probably because I need to get a new life.
Seriously though, one of my daughters had a group of friends over for the weekend.
They took over the PS3 to play Singstar. There wasn't much else to do, so I hid myself in the study & spent some time on streetview to get away from the noise. My ears are still bleeding.
That particular building was the easy one. It's a bit Art Deco in its design, which made it very easy to spot amongst all the other normal looking warehouses.
